Spectrogram Intensity Color Mappings

I run Audacity 2.0 on Ubuntu Linux 12.04. I'm not sure what the current status of theming support is, but in any event I can't figure out how to change the spectrogram color mapping.

Audacity is a great program, truely, considering all of the editing, generator and filtering capability. But the sickly pink/blue/white spectrogram colors are truely becoming a show stopper for me. It doesn't see a particularly difficult change to provide several selectable mappings for the spectrogram colors.

I am NOT talking about background colors or waveform line colors or the colors of buttons, text etc. I mean the spectrogram intensity colors of the FFT window.

If there truely is no such thing, what would be the expected complexity and skills needed to create one. I am a C++ programmer and it seems rather straightforward at least
at first blush.

Also, concerning the ImageCache.png file. I am not seeing a useful editor for the options in this file. When I use GIMP the result comes out unreadable, apparently because the image is "flattened". What program would you recommend to editing this customization file.

Theme support is considered "experimental", though no-one has actually worked on it for several years.
To enable theme support you need to enable it in Experimental.h before building the source code.
There is some information about building on Linux here: http://wiki.audacityteam.org/wiki/Compi ... rBeginners
